Hi Aldobear.
I think your question could be asked of anyone posting for help on this website, rather than just Janome.
Personally, I do find it satisfying to complete a crossword, puzzle or just about anything that I think worthwhile in life. I think that it's the same for most people.
So it's no mystery to me why people post here for help (for hints or answers) so that they get the satisfaction of completing something.
If, along the way, they get rich themselves or a charity is helped ... there's some upside!
However, I do think it is important that potential 'Answerers' are able to trust that any 'Asker' has put in enough of their own time & effort before coming to this forum.
So please let's all be friendly.
